Having issues with 3-4-2. Change The Peeling Point For Avoiding Led Tilting Within The Cavity by Nichia? Read our step-by-step SMT maintenance solution below. If you require replacement feeders, nozzles, or sensors, contact SMTBOX for OEM-compatible parts.
3-4. Problem 4: LED tilting within the cavity due to vibration of the emboss carrier tape
When an excessive vibration is applied to the emboss carrier tape, LEDs may tilt within the cavities.
LEDs with a lens are susceptible to vibration, resulting in tilting, since its center of gravity is located higher.
3-4-2. Change the peeling point.
When the top cover tape is peeled off from the emboss carrier tape long before the nozzle comes down to absorb an LED, some of the LEDs move around within the space between the feeder cover and the carrier tape, leading to LED tilting.
Please peel off the cover tape just before the nozzle comes down to absorb an LED. Then, LED’s up-and-down movement can be restricted, preventing from LED tilting.
Comparison of the Peeling Positions
Please note that some of the mounters are equipped with a shutter. In such cases, it is impossible to change the peeling position of the top cover tape.
